Am I correct to assume that this is about FX_PAGE_LOAD_MS, TOTAL_CONTENT_PAGE_LOAD_TIME?
Flags: needinfo?(jmathies)
I can't seem to find reference to this in either of the rc docs. Vladan, do you remember what you wanted to do here?

Yes + HTTP_PAGE_* probes

This is covered by "we need better measures for startup + page-load time, not just time-to-first-paint" and "Review if page-load time histograms are reflective of real-world performance
" in the "Evaluating Real-World E10S Performance" google doc.

The essential idea is to verify that these probes correspond to what the user sees, and to add new probes if they don't reflect actual page-loading performance

Splitting in several bugs. I'm handling FX_PAGE_LOAD_MS in bug 1228020.
For reference, here's the list of HTTP_PAGE_*

"HTTP_PAGE_DNS_ISSUE_TIME"
"HTTP_PAGE_DNS_LOOKUP_TIME"
"HTTP_PAGE_TCP_CONNECTION"
"HTTP_PAGE_OPEN_TO_FIRST_SENT"
"HTTP_PAGE_FIRST_SENT_TO_LAST_RECEIVED"
"HTTP_PAGE_OPEN_TO_FIRST_RECEIVED"
"HTTP_PAGE_OPEN_TO_FIRST_FROM_CACHE"
"HTTP_PAGE_OPEN_TO_FIRST_FROM_CACHE_V2"
"HTTP_PAGE_CACHE_READ_TIME"
"HTTP_PAGE_CACHE_READ_TIME_V2"
"HTTP_PAGE_REVALIDATION"
"HTTP_PAGE_COMPLETE_LOAD"
"HTTP_PAGE_COMPLETE_LOAD_V2"
"HTTP_PAGE_COMPLETE_LOAD_CACHED"
"HTTP_PAGE_COMPLETE_LOAD_CACHED_V2"
"HTTP_PAGE_COMPLETE_LOAD_NET"
"HTTP_PAGE_COMPLETE_LOAD_NET_V2"

I'll try and pick a few of these.
All done.
